Register Type Trunk

You could use the ‘IP Ping’ tool to check the network status of device.

Ping is a basic Internet program that allows a user to verify that a particular IP address exists and can accept requests. Ping works by sending an Internet Control Message Protocol (ICMP). Because the processing of the SIP packet is at the application layer and the ICMP packet is at the network layer. So if the ping works doesn’t mean the sip trunk should be registered with the end device.
